FoxCount

Questions answered by this recipe

How can I display the number of words or characters already entered or remaining in an input or a textarea input element?

Description

FoxCount provides four new directives:

(:foxcharcount inputname:) and (:foxwordcount inputname:) which count the number of characters or words already entered in an input or a textarea input element.

(:foxremainingchars inputname maxchars:) and (:foxremainingwords inputname maxwords:) which count the remaining number of characters or words to be entered in an input or a textarea input element.

"inputname" is the value the input element or textarea "name" attribute to count the words or characters for.

"maxwords" is the maximum number of words the input element should display. The number of remaining words is simply (maxwords - count of words). Note that the maximum number of words is not enforced on the input or textarea element.

"maxchars" is the maximum number of characters the input element should display. The number of remaining characters is simply (maxchars - count of characters). Note that the maximum number of characters is not enforced on the input or textarea element.

maxchars can also automatically be deduced from the maxlength element attribute (see https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/maxlength). In this case the maximum number of characters is enforced on the input or textarea element.
